I'll say it again: it has to run fast in ksh. And no, prngd cannot pass diehard. The output from /dev/random and /dev/urandom also flunks diehard for sunos and linux. Passing diehard is tough.

A sample run:

Code:

>>}###@>---- CvccvE-n
Template EEEEEEEE has 2,992,179,271,065,856 possibilities
Template CvccvE-n has 2,389,338,000 possibilities

Vephu}:6     VICTOR echo papa hotel uniform right-brace colon six
Sawtu]!7     SIERRA alpha whiskey tango uniform right-bracket exclamation seven
Yuywud-0     YANKEE uniform yankee whiskey uniform delta hyphen zero
MuwsaQ:4     MIKE uniform whiskey sierra alpha QUEBEC colon four
Yaqka%.7     YANKEE alpha quebec kilo alpha percent period seven

>>}###@>----

Each of those 2,389,338,000 possibilities must be absolutely equiprobable. And the selections chosen must be completely unpredictable. Achieving both goals simultaneously is not a piece of cake. And yes, RNGs are notoriously non-portable. I want to do all of this in a self-contained portable shell script.

ISCSI.CONF(5)							File Formats Manual						     ISCSI.CONF(5)

NAME

       iscsi.conf - iSCSI Target and LUN configuration

SYNOPSIS

       /etc/iscsi.conf

DESCRIPTION

       This manual page describes the format of the /etc/iscsi.conf file. This file is a simple text file that iscsid(8) uses to locate iSCSI tar-
       get devices and LUNs.  Comments are marked by lines beginning with '#'.

       Available entries include:

       DiscoveryAddress=<address>
	      IP address or hostname to use for target discovery.  A TCP port number may be specified by appending a colon followed  by  the  port
	      number. This entry must start in the first column, and must not contain any whitespace.

       TargetIpAddr=<address>
	      A synonym for DiscoveryAddress.

       Username=<user>
	      Specify  the  authentication user.  If this entry precedes all DiscoveryAddress entries, it serves as the default.  If this entry is
	      indented under a DiscoveryAddress entry, it specifies the user for all targets discovered at that IP address.

       Password=<pass>
	      Specify the authentication password for the previously listed iSCSI If this entry precedes all DiscoveryAddress entries,	it  serves
	      as  the default.	If this entry is indented under a DiscoveryAddress entry, it specifies the user for all targets discovered at that
	      IP address.

EXAMPLE

       # set the default user and password
       Username=alice
       Password=nty57nbe

       # targets at this address will use the default Username and Password
       DiscoveryAddress=192.168.10.94

       # targets at this address will use the Username and Password below
       DiscoveryAddress=192.168.10.95
	   Username=beatrice
	   Password=93fdgc20
